Plastering work in new construction was poorly done, any experiences?

Hard to see on the phone. It just looks spotty - was it painted?

It looks "wavy" in the pictures. Are those brick walls or timber studs covered with drywall?

Yes, it is partially really wavy. The mirror in the bathroom stands about one centimeter away from the wall due to the unevenness.

Looks "wavy" in the pictures. Are those masonry walls or timber studs covered with drywall?

And they are masonry walls. The plasterers blame the bricklayers.

I would say: It is not nice but also not a defect. No chance of getting anything through there. Grazing light is also not allowed for defect assessment. At least two pictures are taken in grazing light.

Thank you for the answer. How do I have to look at the wall so that it is not grazing light? I always see the waves, even at night when the light comes from above.

Light from above is also sidelight. It must either be completely diffuse or come from the front. Although more than one centimeter difference would already be extreme. There is definitely a standard for that. Unfortunately, I don't know which one.

What quality was agreed upon? Q2 or q3?

So this is what my first plastering attempts looked like partly (but sometimes even worse^^). Were those professionals and if so, what had you agreed on? Were the walls already very uneven beforehand? I wouldn't be satisfied with it either. Not if it was done by a professional and if it is in the living area.
